Abstract：
An improved Glauber theory for calculalions of the total reaction cross section at low and medium energies is proposed. The quantum effect,Coulomb effect and isospin effect of nucleon-nucleon collision inclnded in the improved Glauber theory are discussed under the assumption of the effective nuclear density distribution. It is found that quantum corrections is very important when the Glauber theory is applied to calculations of the nucleus-nucleus reaction cross. The calculated results obtained with the improved Glauber theory are in agreement with the experimental data in ten percent without any free parameters,which demonstrate the improved Glauber theory to be a pragmatic approach for calculating total nucleus nucleus reaction cross sections in the low and intermediate energy regions.
